Well, losing your blog, and your services, will be a very sad loss, but I can hardly blame you for deciding that enough is just enough. If I had required an ambulance whilst living in London, I would have felt honoured to have been treated by you. And this is coming from the daughter of a surgeon and sister of a nurse. However - I'm about your age (just turned 37), and if I were in your shoes I would leave the LAS so fast radar guns would not work (due to the copious amounts of dust, and also Doppler). I wish you all the very best in whatever you decide to do next. Good luck!! :-)
